VM Box problem

I am on Windows 7, Intel Core i3-2120 CPU. I’ like to install Win 95 as a guest system. I am using the Virtual Box Graphic User Interface v.4.2.6 r82870.
Now,in Windows 95 there is ( or was!) a separate boot diskette to be inserted in the physical floppy drive before inserting the OS installation CD. My computer is recent. I have no floppy drive on it and I don’t see any setting in VM Box giving me the option to boot from an image file through a virtual floppy. Neither do I see anything to configure the CD-Rom drive , whether virtual or physical with a path to the image file of the installation disc..

Anyway, going by trial and error, I have created a Virtual Box new machine and configured the Bios as directed.
I have burned the image file of the Ms-Dos 6.22 boot disc on a CD and inserted it into the CD-Rom drive. When I power it on, all I get is an error message” ‘Fatal: could not read from the boot medium. System failed.”
( incidentally, the DOS boot disc must be good, because it worked in VMWare and I was even able to install win 95 on it. Unfortunately, I had a H.D. failure. I had to reformat it and I tried for three days to re-install win 95 on VMWare, without success. God knows why. This is why I decided to try Virtual Box, which looks a LLLOT simpler, or may be too simple! Unfortunately, this time I can’t even get it started!

I don’t know if I have the right version of Virtual Box. In their site there are quite a few and I am a bit confused

Thank you jamieamunra.
O.K. up to step 3
At step 4 in the storage tree the first item is”Controller Floppy ( empty) “. By right clicking on it, I am asked if I want to add a floppy device. I click and then I get to a question prompt “ you are about to add a new floppy drive. Would you like to choose a virtual floppy disk to put in the drive or leave it empy for now?”. Which do I choose? Also, I can’t see a “ Choose disk” prompt.

When I click on the “ Green Plus sign” I am prompted to choose “ create disk” or “leave it empty”.
If I select “Choose disk”, I get a screen prompting me to choose a virtual floppy disk file. This screen is empty. Only if I select “ all files” do I get the screen populated with 4 files (Vbox, VBoxlog.1, Vboxlog.2 and Vboxlog.3. But I don't think these are the files needed. This is all. What do I do?

OK first you have to create the .img file that is the virtual floppy disk image from the Win95 boot disk files.
you can use something like WinImage http://www.winimage.com/winimage.htm
Once you have created the boot disk image mount it into the virtual floppy drive that you created in your virtual Windows 95 machine by following my previous steps.
Good luck
